I have a 96 civic with an obd1 b18c. when the water temp is cold the car runs fine, but as soon as the water temp gets to normal operating temp. it starts to bog down anywhere between 2500 rpm and 4000 rpm. anything over 4000 rpm it runs fine. it mainly happens at a cruise speed when i go to pick up the throttle a little bit it will bog down but if i give the throttle a little shot of gas it pulls out of it, it is also an intermittent problem. it comes and goes. last night i drove it home from work which is about 10 km and it ran like shit the whole way but after i let it sit for about 45 minutes i drove out to my girlfriends which is about 15 km and it ran fine the whole way. it also sometimes happens from a stop when pulling away but only once in awhile it mainly happens while cruising. any help would be awesome
